In this episode, we will cover the German surgeon August Bier, and his creation of both spinal anesthesia, and the eponymously named Bier block, used commonly today for regional anesthesia. We'll also cover some less well known aspects of his career, and touch on his mentor, Johann von Esmarch, known for the Esmarch bandage (and so much more)! Of course, along the way, we'll meet up with some other players in the history of medicine and surgery. Finally, we will talk about one of Bier's greatest legacies, the Sauen forest in Germany. You'll have to listen to find out more!
